The Impact of Bariatric Surgery on Polycystic Ovary Syndrome: a Systematic Review and Meta-analysis.
Synthesis in Obesity surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 56 papers, 7 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
Bariatric surgery has been proven to be a successful management strategy for morbid obesity, but limited studies exist on its effect on polycystic ovary syndrome (PCOS). A comprehensive search of electronic databases was completed. Meta-analysis was performed on PCOS, hirsutism, and menstrual irregularity outcomes following bariatric surgery. Thirteen primary studies involving a total of 2130 female patients were identified. The incidence of PCOS preoperatively was 45.6 %, which significantly decreased to 6.8 % (P < 0.001) and 7.1 % (P < 0.0002) at 12-month follow-up and study endpoint, respectively. The incidences of preoperative menstrual irregularity and hirsutism both significantly decreased at 12-month and at study end follow-up. Bariatric surgery effectively attenuates PCOS and its clinical symptomatology including hirsutism and menstrual irregularity in severely obese women.
